Card Machine for a UK High-Risk Vertical
UK high-risk verticals (adult content, CBD products, crypto, gambling, debt advice, vape, firearms, weight loss, dating, travel, telemedicine) usually need a specialist acquirer rather than a mainstream provider. Trust Payments, Acquired.com, ePayments, World Pay's high-risk arm, and specialist brokers serve the sector. Rates run 2 to 4 per cent versus 0.5 to 1.0 per cent for mainstream verticals. Rolling reserves of 5 to 10 per cent are normal. Approval is slower (5 to 14 days) but more durable.
What this means for your business
High-risk in card payment terms means an MCC (merchant category code) that carries elevated chargeback rates, regulatory complexity, or reputational sensitivity. The MCC list is set by Visa and Mastercard. Verticals routinely classified high-risk in the UK include adult products and services, CBD and cannabis-adjacent products, cryptocurrency exchanges, gambling, debt advice and IVA companies, vape and e-cigarette retail, firearms and ammunition, weight loss programmes, dating services, travel agents, and telemedicine.
Mainstream acquirers (Worldpay, Elavon, Barclaycard, Lloyds Cardnet, NatWest Tyl, Dojo, SumUp, Zettle, Square) decline most high-risk applications by default. They have onboarded acceptance rules tuned to mainstream SMEs and will not deviate. Specialist high-risk acquirers (Trust Payments, Acquired.com, ePayments, World Pay's high-risk arm) have purpose-built underwriting for these verticals, accept the higher chargeback rate as part of their pricing, and provide sector-specific dispute support.
Pricing reflects risk. High-risk transaction percentages run 2 to 4 per cent versus 0.5 to 1.0 per cent for mainstream verticals. Rolling reserves of 5 to 10 per cent of monthly volume are routine, held for 90 to 180 days against chargeback exposure. Setup fees and monthly fees are usually higher (£50 to £200 monthly is typical). The trade-off is durability: a specialist acquirer that has approved a high-risk business is far less likely to freeze the account later than a mainstream facilitator (Stripe, PayPal) that approved on automated criteria and reviews after the fact.
Key points
- High-risk MCC list is set by Visa and Mastercard, covers adult, CBD, crypto, gambling, debt, vape, firearms, weight loss, dating, travel, telemedicine
- Mainstream acquirers decline most high-risk applications by default
- Specialist acquirers (Trust Payments, Acquired.com, ePayments) serve the sector
- Rates 2 to 4 per cent versus 0.5 to 1.0 per cent mainstream
- Rolling reserves of 5 to 10 per cent for 90 to 180 days are standard
- Setup takes 5 to 14 days versus 1 to 3 days mainstream
- Specialist approval is more durable than facilitator approval, lower long-term freeze risk
Common pitfalls
- Trying to set up on Stripe or PayPal and being frozen mid-trading, the facilitator model is the wrong fit for high-risk
- Misclassifying the business as a lower-risk vertical to get approved, this surfaces at the first chargeback wave
- Not factoring the higher rate into pricing, high-risk businesses need higher gross margin to absorb the processing cost
- Forgetting that specialist acquirers run full underwriting, the application takes longer but the outcome is more durable

Is my business high-risk if it sells supplements but not CBD?
Probably not. Mainstream supplements (vitamins, protein, weight management without explicit medical claims) are usually mainstream-risk. The line is drawn at medical claims, controlled substances, weight-loss programmes with rapid claims, and any cannabis-derived product. If unsure, a specialist broker can pre-classify before application.
How long is a typical high-risk merchant relationship?
Once approved and trading clean, high-risk merchant relationships often run 3 to 5 years without issue. The hardest part is approval, not retention. Specialist acquirers value retained accounts and provide rate reviews at 12, 24 and 36 months as trading history builds.
